Abstract.We discuss various views and conceptual frameworks put forward in the discussion of ICT and sustainable development: An optimistic and a pessimistic view of ICT with regard to sustainability, the three-pillar approach to sustainable development, the three-level approach to ICT impacts, the claim of human, social and ecological compatibility of ICT and the plain use of ICT for development. We show that each of these approaches has its problems and limitations and conclude with formulating the challenges of finding an analytical approach which will effectively support decision-makers in using ICT in the service of sustainable development.

For 40 years, the academics and business executives who have attended the Human Choice and Computers international conference series have discussed human choices and social responsibility in relation to information and communication technology (ICT). At this 2012 conference, the focus is on ICT critical infrastructures, and the challenges they pose to governments, businesses and people. Several topics have emerged as relevant in this conference: ICT developments at international and national levels; sustainable and responsible innovation; dilemmas involving ICT, peace and war; and the implications of ICT and social media for citizens' involvement and citizens' rights. What should national computing associations be doing to explore these serious issues? How should the International Federation for Information Processing (IFIP) itself respond? Responses are needed that are flexible and durable enough to face the challenges of the coming four decades.

The availability and promise of social networking technologies with their perceived open philosophy has increasingly inspired citizens around the world to participate in political activity on the Web. Recent examples range from opposing public policies, such as government funding cuts, to organizing revolutionary social movements, such as those in the Middle East and North Africa. Although online spaces create remarkable opportunities for various forms of political action, there are concerns over the power of existing institutions to control and even censor such interaction spaces. The objective of this article is to draw together different insights on the online engagement phenomenon, highlighting both its potential and limitations as a mechanism for fostering democratic debate and influencing policy making. We examine recent examples from Europe, the Middle East and Latin America. Finally, we summarize the implications of our work and outline directions for further research.
